Does the PORTACOUNT work with self contained breathing apparatus (SCBA) such as used by fire fighters?
Yes. However, to really test the fit of the face piece, the respirator must be tested in negative-pressure mode using Class 100 (HEPA) filters. This is most often accomplished by using an identical face piece in a negative-pressure version with HEPA filters. Most respirator manufacturers offer negative-pressure versions of the same face piece used for their SCBAs. OSHA and ANSI are endorsing this method. Testing may be done with the air supply on. However, this is performance testing, not fit testing. If tests are to be done with supplied air, the particles in the supplied air must be removed with a HEPA filter prior to delivery to the mask. Grade D breathing air is not particle free.
